Abstract
The utility model discloses an engine bracket lower support piece which comprises a tube body and an inner hole. The tube body is a cylindrical tube body. A frustum is arranged at the lower end of the tube body. The inner hole of the cylindrical tube body is a circular inner hole. The frustum comprises an ellipse inner hole. The ellipse inner hole, the circular inner hole and the cylindrical tube body are concentric. According to the engine bracket lower support piece, the reliability of products can be improved, service life is prolonged, processing technology is simple, and cost can be lowered.
Description
Technical field
The utility model relates to the technique of pipe field, particularly relates to a kind of engine holding frame lower support element.
Background technology
Nowadays, automobile transverse engine pattern relatively more in vogue, therefore, the bottom bracket that is positioned at driving engine drive belt front end plays a part very important.No matter be up and down or the rocking of front and back, all can exert an influence to bottom bracket.After car has used a period of time or mileage, wearing and tearing or distortion may appear in its engine bottom carriage, then, when you drive to stop halfway, you can feel driving engine in shake, and it also is not very serious may shaking, but when your starting, and travel that you can feel that driving engine sends the dull sound when accelerating, and may also tremble.This is because the high temperature in the engine case and greasy dirt etc. cause.This phenomenon is nowadays very general in the car engine machine enclosure., therefore, the strut member of periodic inspection or replacing bottom bracket, make it have enough load-carrying capacitys.
The utility model content
The technical matters that the utility model mainly solves is: for the deficiencies in the prior art, provide a kind of engine holding frame lower support element, can improve product stability, increase the service life, reduce cost.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of engine holding frame lower support element is provided, comprise: body and endoporus, described body is the cylindrical shape body, its lower end is provided with frustum, the endoporus of described cylindrical shape body is circular inner hole, and described frustum comprises oval endoporus, and described oval endoporus and described circular inner hole are concentric with described cylindrical shape body.
In preferred embodiment of the utility model, the concentricity of described oval endoporus and described circular inner hole and described cylindrical shape body is less than or equal to 0.015mm.
In preferred embodiment of the utility model, the material of described engine holding frame lower support element is the 20# solid drawn pipe.
In preferred embodiment of the utility model, the surface of described body, circular inner hole and oval endoporus is smooth layer.
The beneficial effects of the utility model are: the utility model has disclosed a kind of engine holding frame lower support element, the employing carbon constructional quality steel is material, adjust the engine bottom carriage by the profiled holes of frustum section, can improve product stability, install more firm, high temperature resistant, corrosion prevention, can increase the service life, reduce cost.
Description of drawings
Fig. 1 is the structural representation of the utility model engine holding frame lower support element one preferred embodiment;
The mark of each parts is as follows in the accompanying drawing: 1, body, 2, endoporus, 21, circular inner hole, 22, oval endoporus, 3, frustum.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
See also shown in Figure 1ly, the utility model embodiment comprises:
A kind of engine holding frame lower support element, its material selection 20# solid drawn pipe comprises: body 1 and endoporus 2; Described body 1 is the cylindrical shape body, the lower end is provided with frustum 3, the endoporus of described cylindrical shape body is circular inner hole 21, the endoporus of described frustum 3 is oval endoporus 22, described oval endoporus 22 and described circular inner hole 21 are concentric with described cylindrical shape body, and its concentricity all is controlled in the 0.015mm.
Wherein, the surface of described body 1, circular inner hole 21 and oval endoporus 22 is smooth layer.
Engine holding frame lower support element of the present utility model is selected the 20# solid drawn pipe, and the profiled holes of its frustum section adopts cold drawn forming, can guarantee that it reaches target hardness, and internal material is not organized and can be changed, the difficult crack that produces; Concentricity is controlled in the 0.015mm, can guarantee its product stability, and it is installed firmly, is difficult for displacement, and has enough load-carrying capacitys.
The utility model has disclosed a kind of engine holding frame lower support element, and the employing carbon constructional quality steel is material, adjusts the engine bottom carriage by the profiled holes of frustum section, can improve product stability, install more firm, high temperature resistant, corrosion prevention can increase the service life, and reduces cost.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification sheets and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
